Types of Tubing
This type of tubing is often used for evaporators and some newer heat exchanger designs.
What is aluminum tubing?
This tool is used for cutting smaller, soft copper tubing.
What is a tubing cutter?
This type of connection uses a 45° angle with SAE fittings and is typically used for smaller tubing.
What is a single flare?
When soldering, you should wear eye protection with this type of lens or darker.
What is a No. 2 filter lens?
This tool is used to remove inside burrs after cutting tubing.
What is a reamer or deburring tool?
This tubing is resistant to corrosion and often used in food processing applications.
What is stainless steel tubing?
When using this tool to cut tubing, you should use a blade with a wave set pattern and 32 teeth per inch.
What is a hacksaw?
This method of joining tubing requires temperatures above 840°F (450°C).
What is brazing?
This dangerous gas is a by-product of some refrigerants when exposed to an open flame or extreme heat.
What is phosgene gas?
This equipment setup mixes pure oxygen and acetylene to produce a hot flame for brazing.
What is oxyacetylene brazing equipment?
This type of copper tubing is sold in rolls and can be softened by annealing.
What is soft ACR tubing?
This process involves heating copper tubing to a dull cherry red and allowing it to air cool slowly.
What is annealing?
This process uses adhesion and capillary action to join water supply and drain lines.
What is soldering?
This device prevents flame from traveling backward into the hose and supply tank in oxyacetylene equipment.
What is a flashback arrestor or check valve?
This tool is used to form single or double flares on tubing.
What is a flaring tool?
This type of pipe is used for water, drain, and vent lines, but never for refrigerant circulation.
What is non-refrigerant tubing and pipe?
This tool makes manually bending tubing easier and reduces the danger of flattening.
What is a bending spring?
This type of connection is used to join aluminum tubing to copper tubing when the technician is not familiar with aluminum brazing.
What are mechanical fittings or tube couplings?
When brazing, it's advisable to wear this type of filter lens or darker.
What is a No. 4 filter lens?
This type of swaging tool uses hydraulic pressure to expand tubing.
What is a hydraulic swaging tool?
This type of steel pipe is primarily used for gas lines.
What is black pipe?
When bending tubing with a lever-type bender, you should align these marks before bending to the degree mark.
What are the zero marks?
This method of joining plastic pipe involves using a primer to clean and soften bonding surfaces.
What is solvent welding?
This non-flammable gas is used as a purging agent before brazing to remove air, vapors, dirt, and moisture from tubing.
What is nitrogen or carbon dioxide?
This tool is used to cut plastic pipe and ensures a square cut.
What is a fine-tooth saw with a miter box?
